Newborn Skull (CT, vertex view) Showing Anterior and Posterior Fontanels
Computed Tomography (CT) scan with 3D surface-rendered reconstruction of vertex view newborn skull with fontanels (fontanelles) and sutures. Cranial vault bones usually ossify from the center to periphery, which results in this “widened” appearance of the sutures in the newborn.
- Anterior Fontanel (bregmatic fontanelle) - largest fontanel located at the junction of the sagittal, coronal, and frontal sutures. In the newborn it is lozenge-shaped and measures about 4 cm in its antero-posterior and 2.5 cm in its transverse diameter.
- Posterior Fontanel - located at the junction of the sagittal and lambdoidal sutures and is triangular-shaped.
- Lateral Fontanels - laterally located and correspond respectively with the sphenoidal and mastoid angles of the parietal bones, and are small irregular shaped.
